Can it be used in conjunction with a DLNA server like MiniDLNA? The problem with DLNA servers I have tried is they present vdr recordings as a list of 1.ts files which is not user friendly. Does it support H264 vdr recordings? I'm looking for a solution to view HD recordings on a TV using a thin client, like a DLNA client for example.

Just make MiniDLNA's config point to the vdrnfofs file system. But I have no idea, if the *.nfo files are of any use to DLNA devices.

It doesn't care about the encoding. The VDR files are just virtually concatenated and presented as a single *.mpg file.

Re: [vdr] vdr-checkts + vdrnfofs
I tried to set up a dlna server with an earlier version of vdr-nfofs a few months ago. It kinda worked but there were some performance problems in regard to file system operations. I hacked a file descriptor cache into the python code which helped a bit. Tobi might have included this in the new version.

You can try my patchset but I haven't worked on that for some months now. Patch is not minimal and not cleanly separated, so you should pick the tidbits you like.

But I miss one thing. When you create the filename you include the Recording-Timestamp at the end of the filename. So you can only sort these files in the browser alphabetically. But it would be nice to have these timestamps as the creation time of the mpeg-file and not only "1.1.1970 1:00". Then you it would be possible to sort also based on the date column. I would prefer this because I normaly look the oldest unseen recordings first. Is it possible to include this in one of the next versions?
